Mycobacterium smegmatis expressing Rv1717 shows altered colony morphology and cell wall (CW) associated properties. (A) On MB 7H10 agar, M. smegmatis harboring empty vector (MsmpMV261) formed rough colonies with irregular margins, while M. smegmatis expressing Rv1717 (MsmRv1717) formed smoother colonies with more regular margins. (B) Accumulation of EtBr and (C) Nile red by MsmpMV261 and MsmRv1717 (D) MsmRv1717 and MsmpMV261 were left untreated or treated with 0.05 or 0.1% (w/v) Sodium dodecyl sulfate (SDS) for 3 and 6 h. Viable cells in all samples were estimated by CFU assay. Statistical significance of data wherever applicable is indicated by ns: p > 0.05; ***p < 0.001. Data plotted are mean ± SD of three independent experiments.
